[LLVMdev] Proposal for safe-to-execute meta-data for heap accesses
...bunch of places, (b) wasn't a big deal, and (c) reliably scaled to 8 cores (the max number of cores I had at the time - I was a grad student and it was, like, the last decade). Is there any documented proposal that lays out the philosophy? I'd like to understand why locks are such a party pooper. > to require careful locking protocols to be followed. Instead, I want the design to naturally arrange for different threads to operate on different constructs and for the interconnecting interfaces to be thread safe. The best system we have yet devised for this is based around function passes...

Universal syntax for Markdown
Hi, because of the great editor "Writer" from Information Architects I've learned about Markdown and I love it. But it's very confusing, that there are so many standards with different features: classical Markdown, Markdown Extra, MultiMarkdown. I think for most users and the spreading of Markdown it would be nice, to have only one syntax. And this universal syntax should have
